Made of borosilicate glass for clarity, strength, heat-, and chemical-resistance
Wide funnel mouth: the wide funnel mouth is easy to pour liquid and not easy to leak.
Sand core funnel is suitable for the pharmaceutical industry, biological product factory, chemical industry and other units to filter larger capacity solutions. G6 sand core funnel is also known as bacterial funnel, and suitable for some heat-sensitive drugs, and it is more suitable for sterilization by non-heating.
It is often used to extract crystals in organic chemistry experiments. After the filtration in this case is completed, a small amount of pure solvent can also be used on top to wash away impurities on the crystal surface.
Great for Professional Laboratories, Classrooms & Household; Superior chemical durability and heat tolerance. Designed for use in professional laboratories, but is an ideal choice for science classrooms and household use.
